5 years before I was born my mom was just messing around and having fun, then she went to a fortune teller to just joke and well... the fortune teller told her she was gonna have a kid 5 years from now and it was going to be an old soul and, after she told me this I got a bit curious, does anyone know a good see your past life spell? I know it's silly but I want one that works well.
there are books and plenty of information on doing past life regression. Have you researched this area yet? Perhaps seek out a channeler who can help provide the information you are seeking.
good luck on your journey
There are some hypnotists who provide past life regression services. I think a soul's age doesn't refer to how long it's existed, but the number of lives lived specifically on Earth. To be an old soul is to be an experienced soul who has learned much from previous lives.
